Are there have strokes when you purchase solar powered led street light?

        In the process of purchasing solar powered led street light,there are three tricks, need to notice: Firstly,solar powered led street light panel classification:The main function of solar cells is to convert light energy into electrical energy. This phenomenon is called photovoltaic effect. Among the many solar cells, the more common and practical ones are mainly monocrystalline silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cells.From the material category: mono crystal silicon conversion efficiency of up to 18%, polycrystalline silicon 16%, amorphous silicon less than 16%.

         From solar powered led street light solar panel high and low conversion efficiency,mono crystal silicon grade A,grade B, grade C, polysilicon grade A, grade B, grade C, polysilicon grade A, grade B, grade C.A grade solar panel conversion efficiency of up to 16 or more, B grade is lower than A grad.The level of C is lower than 8%, the conversion efficiency is higher, and the conversion efficiency is lower.Therefore, when you want to purchase, you need to know the requirements for solar powered led street lights olar panels (photovoltaic modules, power panels), and select the appropriate level of solar panels. Secondly, the advantages and disadvantages of solar powered led street light poles.Good solar powered led street light require high quality poles to support. The poles are mainly divided into equal-diameter rods (same as the pole’s upper and pole’s lower),tapered rods (smaller upper diameter, larger lower diameter), and special-shaped rods.The main body of the lamp post is an all-steel structure and an overall hot (cold, electric) galvanizing/spraying (powder) treatment. Very popularly speaking,the quality of the pole depends on the conscience of the manufacturer. If the caliber is to meet the contract requirements, but the wall thickness is not up to the requirement.Required thickness 3.0,the factory made 2.5.(cold, electric) galvanizing is said to be the overall heat.Galvanized,there is the thickness of the galvanized layer / spray (powder) layer.The purchaser should know that the height of the pole is determined by the width of the road, the spacing of the luminaires, and the illuminance standard of the road.

         Thirdly,solar powered led street light system performance testing methods.First,the solar cell power must be some times higher than th Led lamp power,and the system can work normally.Second, the battery capacity must be 3-6 times higher than the daily power consumption of the Led lamp. There are too many manufacturers of solar powered led street light in the current market, and the quality of products varies.If the above parameters are not met, the system will not work properly or can not reach the normal time to continue working.
